UNITED STATES PATENT OFFICE.

OIL-CAN.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Application filed December 19, 1904;. Serial No. 237,489.

To all whom it may concern:

Be it known that I, THOMAS B. WILKINSON, a citizen of the United States, and a resident of Rivera, in the county of Los Angeles and State of California, have made certain new and useful Improvements in Oil Cans, of which the'following is a specification.

.My invention is an improvement in oil-cans, and has for an object to provide a novel construction whereby the fluid contents of the can may be forcibly ejected through the spout by a pumping action; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawing the figure is an elevation, partly in section, of an oil-can embodying my invention.

As shown, the oil-can includes the can or body A, having at one side the handle B and provided with the bottom 0 and the neck D, with which connects the lower end of the spout E, which latter may be of any suitable length to properly reach the object it is desired to oil.

The body or can A is crossed by the cylinder F, which extends diametrically through the can about midway between its bottom and nec is suitably secured near its ends to the body A, and projects beyond the said body and is threaded to receive the filling-cap G and the opposite cap H, the latter being provided with a stufling-box it, through which the piston-rod projects, as shown in the drawing. This cylinder F is provided near its lower or discharge end with an opening I, through which the fluid may pass from the can into the lower end of the cylinder, and the upper or discharge end of the cylinder is connected by a connecting-tube J with the lower end of the neck D, the connecting-tubeJ communicating at its upper end, at J, with the lower end of the neck D, as clearly shown in the drawing.

At its lower end the cylinder F is threaded internally at K to a point in advance of the feed-opening I, and the valve-plug L, having an inwardly-opening valve L, is screwed into such end of the cylinder to a point in advance of the opening I, being provided with sockets L for engagementbya double-pointed wrench, so the valve-plug may be readily screwed into and out of the cylinder.

The piston M, having the valve M, operates in the cylinder Fabove the valve-plug L and is provided with the piston-rod M and the readjusting-spring M by which the piston is returned after operation by the operator. The piston-rod M extends through the studing-box H and connects with the pull-bar N, whose ends N are guided in slots N in the handle B.

It may in operation be desirable to vent the body of the can, and this may be done by means ofa venting-valve O in a filling-cap 0, arranged as shown in the drawing.

The body of the can may be filled at O, or the cap G may be removed to permit the filling of the can through the opening I, and this cap G also permits the ready application, removal, and adjustment of the valve-plug, as may be desired.

Spouts of any length can be used whereby the operator standing on the floor can oil overhead shafting or pulleys or oil intricate machinery without endangering life and limb climbing around the running machinery. In practice the barrel or cylinder F is preferably rigidly secured to the body of the can by soldering or otherwise, but it will be noticed the parts are all readily accessible to repair. It will also be understood that while the invention is specially designed for use in an oil-can it may be employed to spray flowers, nursery stock, or for other uses where it is desirable to force fluid from a can through a spout,

It will be noticed that the pull-bar is conformed generally to the hand and gives the operator great power by which to force liquid out of the can, so that the heaviest grades of oil can be forced out cold and for use on locomotives will be found very desirable, strong, durable, and practically indestructible, the cans being made of heavy compressedsteel with all parts interchangeable.

In operation to discharge the oil the operator grasping the handle of the can and the pull-bar will press the latter up against the handle and will eject the oil by the action of the piston through the connecting rod and spout, as described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The improvement in cans herein described comprising the body or can provided at one side with a handle and with a neck and a spout extending therefrom, the cylinder or barrel extending diametrically through the can and secured thereto near both ends and projecting at such ends beyond the can, the

filling-cap on one end of the barrel, the cap on the other end of the barrel and having a stufiing-box, the barrel being provided near one end With a filling or feed opening and threaded internally from such end to a point in advance of the feed-opening; the valveplug screwed in said threaded end of the barrel to a point in advance of the feed-opening, the connecting-tube connecting the end of the cylinder opposite the feed-opening, with the neck of the can, the piston operating in the cylinder and having its rod extending through the stuffing-box in the end cap and the pull-bar connecting with said piston and guided at its ends by the handle substantially as and for the purpose set forth.

2. The combination with the can, the cylinder and the piston therein, of the handle secured to the can and having guide-slots and the pull-bar guided at its ends in said slots, substantially as set forth.

3. The combination of the can or body, the cylinder therein, and provided near one end with a feed-opening and the cap closing such end of the cylinder and adapted to be removed in order to fill the can, and the operating devices in said cylinder, substantially as and for the purposes set forth.
